As anyone who watched her speech at the Democratic convention knows, Michelle Obama is an impressive woman. She’s quite sincere in her concern for children, too, as evidenced by her “Let’s Move!” initiative–an admirable, sensible approach to fighting childhood obesity. (If you haven’t visited the “Let’s Move!” website, here’s the link. It’s worth a look.)

“Let’s Move!” isn’t just a public relations stunt. Michelle Obama has had considerable success in changing the national conversation on childhood obesity, such as putting mega-food producers on notice. I’d like to see her be more aggressive on fast food industry shenanigans (marketing to kids and such), but for now she’s no doubt held in check a bit by her First Lady gig. It’s definitely a vast improvement over the efforts of past administrations, though.

It will be interesting to see what her future holds. I’m betting she gets the girls off to college (after a second White House term), then enters the political fray herself, with Barack tending the garden back home… Should be interesting, and good for children.
